I spent half the day putting 400 KM on my car (which is a rarity, since I purchased in Oct 2020, my family put 3,000 KM on it) getting all sorts of retro gear. I scoured several thrift shops along the way and met up with two sellers. I got: -8 USB (PS/2 compatible) original Microsoft optical mice - …

Interesting case. Looks like a full height version of the low-profile cases I have (the two on the left). At least, they seem to share a very similar design language. The one on the left is my 286/16 and the other is my 386DX40 PXL_20210305_011600220.jpg There were several indications that this …

After retrobriting the 486 eBay PC, washing the board (some corrosion) and re-badging it (it was labelled a 386,now just AT 1800), I cut a hole in the case plastics and fitted a three 7 segment display. The tint piece is out of an 80s Corolla I got earlier this week when I went to a nearby wreckers. …

Based on mkarcher 's post regarding the jumper settings, I'm tempted to re-try with a 386 again. If I can get that running, I'll put in a 387 😁

Yeah apparently a lot of EISA boards are like that, with two Dallas RTCs, from what I gather. Mine seems to be the odd one out of an already rare setup.

^^^ Yeah I'm gonna go out and say that we probably all know that. Why you're continuing to flame the noob is puzzling, and reminds me of stuff I did on Hyundai Performance boards decades ago ;) I got the girl though, for a while.

EISA card came in (nothing fancy, Qvision Advanced VGA) which took some time to set up, but it does seem to work with no glitches in 320x200 as well as VGA. Going to need to find drivers for it for Windows 3.1 and do something about that backplate staggering. https://i.imgur.com/OBujzoCl.jpg I also …

Looking at pictures of the MAE486 board online there's two Dallas RTC chips, one is for the EISA (the "DS1225Y nonvolatile SRAM") config the other for the RTC and BIOS settings (the classic "DS1287 Real Time"), these two chips have integrated batteries. A common fix is to file down the chip's …

I used to find TONS of cool shit. Now I'm happy if I can find a beige mouse, keyboard, and speakers. Joyous day when I find a 4:3 LCD. I haven't found anything really interesting in a looooooong time.

I didn't expect a reply so soon - I trial and errored it until I found a version that works. http://66.113.161.23/~mR_Slug/EISA/!CPQ3001.CFG/1991-11-06/ My next bet was to manually edit "line 11" and change the values.

That's probably sufficient. I have three systems to span everything from 1985 to 2000. A 386SX 16 covers the early 80s (increasing the wait state from 0 to 1 cripples the machine significantly, sufficient for XT stuff then), a DX4/100 (was originally a DX2/66, can still be one on a whim) for stuff …
